Eurasian Tree Sparrow
Passer montanus
| Conservation status | Small population in North America more or less stable, probably has little impact on native birds. In Eurasia, widespread and abundant. |
|---|---|
| Family | Old World Sparrows |
| Habitat | Farmland, towns. In North America, fairly local in open country with scattered bushes and trees, also in some suburban and city areas. In Europe and Asia, found in many kinds of semi-open habitats, woodland edges, towns, farms. |

Feeding Behavior
Forages mostly while hopping on the ground. May also feed up in shrubs or trees at times. Often forages in small flocks.
Eggs
4-6, rarely up to 8. White to grayish white, marked with brown. Incubation is by both parents, about 13-14 days. Young: Both parents feed the nestlings. Young leave the nest about 12-14 days after hatching, may be fed by parents for another week. One pair of adults may raise 2 or 3 broods per year.
Young

Diet
Mostly seeds and insects. Diet in North America is not known in detail, but undoubtedly includes the seeds of various weeds and grasses, also waste grain in fields. Also eats many insects, perhaps especially in summer.
Nesting
Some adults may remain in pairs at all seasons, or pairs may form well before nesting season starts. Nest: Placed inside a cavity, such as a natural hollow in tree, old woodpecker hole, birdhouse, or hole in building or under eaves. Unlike House Sparrow, seldom or never builds nest in open branches. Nest (probably built by both parents) is a bulky mass of grass, weeds, straw, trash, sometimes lined with feathers.
How Climate Change Will Reshape the Range of the Eurasian Tree Sparrow
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
